I have a general question:
Does this glitch thing only happen on the brushless (Motenergy) motors?
Or on brushed motors (like Agni) too?

Hello Cortez,
My bike is a 2012 X. I have bought another battery now (used at a good price). So I can ride again.
The old battery is still in my cellar waiting for repair.
I will send you a pm regarding your extra bms.

Just wondering what the symptoms are.  My bike was showing fully charged when I set off this morning, then went to zero bars 3 miles into the ride.  I managed to limp home at 15 mph, but not sure if it's a BMS issue or the battery itself, or something else.

Hello Mike,
I have also read your topic...
I was (once or twice) experiencing similar symptoms. But not so dramatic as it was on your bike.
One example: I had 4 bars (of 10) on the "fuel gauge" after approx. 30 Kilometers of riding and the bike shut down the power immediately and the fuel gauge was blinking like it's empty. I was able to drive a few hundred meters with reduced power but then decided to push the bike home. After charging it was OK again. But that was a few months before my BMS failure.

My BMS problem was different...
After a short ride I took the battery (aprox. 80% full) out off my bike because I was about to change the chain and clean the bike. The next day I put the battery back in the frame and I wanted to ride again with my new chain, but the bike did not drive.
Symptoms: The fan, the lights and the speedometer went "on" when I turned the key, just like usual, but when I turned the throtttle, my bike did not move at all. A red "!" was showing on the speedometer.

Thanks for your help to everyone who has replied here. I will let you know if there are any news regarding my old battery/BMS.

Did you have to pay for the replacement BMS?
Or did Zero replace it under warranty?

Hello guys,

The BMS on my 2012 Zero X is dead. My dealer told me that Zero (or more precisely the European Zero Distribution) would possibly charge 600Euro (800$) for a new one.

For some reason it seems my bike has not been sent to Zero for the recall because it looks like my BMS is not covered in silicone http://www-odi.nhtsa.dot.gov/owners/SearchResults?searchType=ID&targetCategory=R&searchCriteria.nhtsa_ids=12V310000
I bought the bike in May 2013 as a demo bike with 5 miles on it. So I´m pretty angry that they try to refuse to repair it under warranty. 

My dealer and I have tested my bike with another 2012 battery and it ran fine.
After that we put my battery in a Zero MX with a stripped down harness (no spedometer, converter, etc.) and it worked fine.
So I`m pretty sure there is no other problem beside the BMS.

In case they dont come up with a satisfying solution, I thought about stripping down the electrics of the bike and ride without BMS from now on.

So here are my questions:

- Do EIG Cells tend to drift?
- If they drift how much would this affect the bikes range or power output?
- Any danger of destroying cells by running without BMS?
- To the guys who have the same Battery: What voltage do you have when its fully charged?


Forgot to mention: My bike has 2300 miles on it.
